Hi All ,

Some time we have to create a file to store some data for our application and also read that file whenever we need it. So in this tutorial we will learn how to create a file on MAC system using python and also reading and writing on file.

1) Create a file :- In this function we just have to provide PATH and FILE_NAME. Please avoid to use private path where special permission is required.

def createFile(path,filename):
    name = path+'/'+filename  # Name of text file coerced with +.txt 
    try:
        file = open(name,'a')   # Trying to create a new file or open one
        file.close()

    except:
        print('Something went wrong! Can\'t tell what?')
        sys.exit(0) # quit Python

2) Write some content to file :- In this function we just have to provide PATH and get user input .User must press enter to finish his input to file.

def writeToFile(path):
    try:
        file = open(path,'a') 
        addToFile = raw_input("please add content to file : ")
        file.write("\n" + addToFile)
        file.close()

    except:
        print('Something went wrong! Can\'t tell what?')
        sys.exit(0) # quit Python

3) Read from file :- In this function we just have to provide PATH and you can see file content on you terminal.

def readFromFile(path):
    try:
        file = open(name,'r')
        with file as ins:
    		array = []
    		for line in ins:
        		array.append(line)
        	print(array)
        file.close()

    except:
        print('Something went wrong! Can\'t tell what?')
        sys.exit(0) # quit Python
